Analysis of intra-fractional positioning correction performed by cone beam computed tomography in SBRT treatments.

Purpose: This study aims to evaluate the positioning correction extracted from Intra-fraction Cone Beam (IF-CBCT) images obtained during Stereotactic Body Radiotherapy (SBRT) treatments, and to assess whether its magnitude justifies its acquisition. In addition, the results obtained in lung, liver, and pancreas SBRTs with two deep inspiration breath-hold systems (DIBH), and for prostate with/without ultrasound (US) monitoring were compared.

Methods: 1449 treatments, performed with two linear accelerators (LINACs) were retrospectively analyzed.

Quality of life and complications in elderly patients after pronation rotation type III ankle fractures treated with a cast and early weight-bearing.

Background: Early weight-bearing is becoming increasingly common because it can positively affect the quality of life of patients. Therefore, the efficacy and safety of this conservative treatment should be assessed for different types of ankle fractures. The goal of this study was to compare early weight-bearing and non-weight-bearing in terms of effectiveness and safety in patients with pronation rotation type III ankle fractures treated nonsurgically.

Orthopedic treatment and early weight-bearing for bimalleolar ankle fractures in elderly patients: Quality of life and complications.

Introduction: Non-operative treatment of Weber's type B ankle fractures is essential in elderly patients. However, there is controversy in the post-reduction management of the fracture between the use of early weight-bearing or traditional treatment and non-weight-bearing for 6-8 weeks. There is limited evidence available regarding which rehabilitation regimen should be included.

Intraspinal metalloma causing lumbar stenosis after interbody fusion with cylindrical titanium cages.

Intraspinal metallomas are rare. The authors present a case after implantation of two titanium threaded interbody cages at the L4L5 level, without posterior instrumentation. To their knowledge this is the first case due to intervertebral cages.

Institutional experience on the treatment of lung and liver lesions with stereotactic body radiotherapy and Novalis Exactrac Adaptive Gating technique.

Introduction: Gating technique can improve the accuracy of the treatment of lung and liver lesions with SBRT, by monitoring organ tumor motion and irradiating within a selected area of the respiratory cycle.

Methods: We have treated 75 patients (34 lung and 41 liver) with Novalis LINAC SBRT Adaptive Gating Technique. A total of 130 lesions, 49 lung lesions (11 primary NSCLC and 38 metastases) and 81 liver lesions (10 primary and 71 metastases).
